Few primary care practitioners offer HIV tests to Hispanic patients in Los Angeles

A study by UCLA researchers found that only 41% of primary care providers offered advice on sexually transmitted infections or safe sex, while 36% had offered more than 20 HIV tests. The study suggests that providers are testing patients who present with symptoms rather than proactively offering early detection.

Man's best friend lends insight into human evolution

Research suggests that the ability of humans to use social cues in cooperative situations may have evolved since the human lineage split from chimpanzees. In contrast, domestic dogs display an innate ability to solve social problems without prior training. This capacity is thought to be linked to the process of dog domestication.
